Description

I was informed that our ftp server has now added
support for TLS. i tried to connect via TLS and
recieved an error message. the server admin told me he
never saw that port-command before, so it could be bug
of some kind.

the command sent is:

PORT 192,168,2,162,4,108

the response is:

500 Illegal PORT command

followed by the error:

Could not retrieve directory listing

please note this only happens while TLS is used to connect.

I just found out that this problem can be resolved by
selecting "passive mode" in preferences
